BACKGROUND OF THE INVENTION

Tyrosine kinases are a class of enzymes that catalyze the transfer of terminal adenosine triphosphate phosphate to tyrosine residues of protein substrates. Tyrosine kinases by substrate phosphorylation are believed to play a critical role in signal transduction for many cellular functions. Although the exact mechanism of signal transduction is still unclear, tyrosine kinases have been shown to be an important contributing factor in cell proliferation, carcinogenesis and cell differentiation.

Tyrosine kinases are classified into receptor type or non-receptor type. Receptor-type tyrosine kinases have an extracellular, transmembrane, and intra-cellular portion, while non-receptor type tyrosine kinases are completely intra-cellular.

Receptor-type tyrosine kinases are involved in a large number of transmembrane receptors with different biological activity. In fact, about twenty different receptor-type tyrosine kinases have been identified. One tyrosine kinase subfamily, referred to as the HER subfamily, includes EGFR, HER2, HER3, and HER4. Ligands of this receptor subfamily include epithelial growth factor, TGF-α, amphiregulin, HB-EGF, betacelulin and heregulin. Another subfamily of these receptor-type tyrosine kinases is an insulin subfamily that includes INS-R, IGF-IR, and IR-R. The PDGF subfamily includes PDGF-α and β receptors, CSFIR, c-kit and FLK-11. Then, there is a FLK family that is involved in the insertion domain receptor (KDR) kinase, fetal liver kinase-I (FLK-1), fetal liver kinase-4 (FLK 4), and fms-type tyrosine kinase-1 (flt-I) . The PDGF and FLK families are usually considered together, due to the similarities between the two groups. For a detailed discussion of receptor-type tyrosine kinases, see Plowman et al., DN&P 7 (6): 334-339, 1994, incorporated herein by reference.

The non-receptor type of tyrosine kinases is also included in many sub-families, including Src, Frk, Btk, Csk, Abl, Zap70, Fes / Fps, Fak, Jak, Ack, and LIMK. Each of these subfamilies is further subdivided into different receptors. For example, the Src subfamily is one of the largest and includes Src, Yes, Fyn, Lyn, Lck, Blk, Hck, Fgr, and Yrk. Src subfamily of enzymes has been associated with oncogenesis. For a more detailed discussion of the non-receptor type of tyrosine kinases, see Bolen Ortcogene, 8: 2025-2031 (1993), which is hereby incorporated by reference.

Both the receptor type and the non-receptor type of tyrosine kinases are associated with a cellular signaling mechanism leading to many pathogenic conditions, including cancer, psoriasis and hyperimmune responses.

Several receptor-type tyrosine kinases and growth factors that bind to them have been suggested to play a role in angiogenesis, although some may promote angiogenesis indirectly (Mustonen and Alitalo, J. Cell Biol. 129: 895-898, 1995) ). One such receptor-type tyrosine kinase is fetal liver kinase 1 or FLK-1. The human FLK-1 analogue is a receptor kinase containing a KDR insertion domain, also known as vascular endothelial cell receptor 2 growth factor or VEGFR-2 because it binds VEGF with high affinity. Finally, the mouse version of this receptor was also called NYK (Oelrichs et al., Oncogene 8 (1): 11-15, 1993). VEGF and KDR are ligand-receptor pairs that play an important role in the proliferation of vascular endothelial cells and the formation and growth of blood vessels, called vasculogenesis and angiogenesis.

Angiogenesis is characterized by overactivity of vascular endothelial growth factor (VEGF). VEGF is also included in the ligand family (Klagsbum and D'Amore, Cytokine & Growth Factor Reviews 7: 259-270, 1996). VEGF binds a high affinity tyrosine kinase receptor KDR comprising a membrane and a related fms-type tyrosine kinase-1, also known as Fit-1 or vascular endothelial cell receptor 1 growth factor (VEGFR-1). Cell culture and gene knockout experiments show that each receptor contributes to different aspects of angiogenesis. KDR mediates the mitogenic functions of VEGF, while Flt-1 appears to modulate non-mitogenic functions, such as those associated with cell adhesion. Thus, inhibiting KDR modulates the level of mitogenic VEGF activity. Indeed, tumor growth has been shown to be sensitive to the anti-angiogenic effects of VEGF receptor antagonist compounds (Kim et al., Nature 362, pp. 841-844, 1993).

Thus, solid tumors can be treated with tyrosine kinase inhibitors, since these tumors depend on the angiogenesis of the formation of blood vessels needed to support their growth. These solid tumors include histiocytic lymphoma, brain cancer, urinary tract, lymphatic system, stomach, larynx and lung,

Including pulmonary adenocarcinoma and small cell lung carcinoma. Other examples include carcinomas in which overexpression or activation of Raf-activating oncogenes (e.g. K-ras, erb-B) is observed. Such cancers include pancreatic and breast cancer. Accordingly, inhibitors of these tyrosine kinases are useful for the prevention and treatment of malignant diseases dependent on these enzymes.

The angiogenic activity of VEGF is not limited to tumors. VEGF is responsible for most of the angiogenic activity produced in or near the retina of the eye in diabetic retinopathy. This vascular growth in the retina of the eye leads to visual degeneration that culminates in blindness. Ocular VEGF mRNA and protein increase in conditions such as retinal vessel occlusion in primates, and decrease pO ₂ levels in mice, resulting in neovascularization. Intraocular injections of anti-VEGF monoclonal antibodies or VEGF receptor immunofusions inhibit ocular neovascularization both in primates and in rodent models. Regardless of causing VEGF induction in human diabetic retinopathy, inhibition of ocular VEGF is useful for treating the disease.

VEGF expression also increases significantly in the hypoxic areas of tumors of animals and humans associated with the area of necrosis. VEGF is also upregulated by the expression of ras, raf, src, and mutant p53 oncogenes (all of which are relevant in the treatment of cancer). Monoclonal anti-VEGF antibodies inhibit the growth of human tumors in nude mice. Although these tumor cells continue to express VEGF in culture, the antibodies do not diminish their mitotic activity. Thus, tumor derived VEGFs do not function as an autocrine mitogenic factor. Therefore, VEGF contributes to tumor growth in vivo by promoting angiogenesis through its chemotactic activity of paracrine vascular endothelial cells and mitogenic activity. These monoclonal antibodies also inhibit the growth of typically less vascularized human colon carcinomas in no-brain mice and reduce the number of tumors arising from inoculated cells.

Viral expression of the VEGF-binding construct Flk-1, Flt-1, murine KDR receptor homologs, truncated to eliminate the cytoplasmic tyrosine kinase region, but while maintaining membrane anchoring, virtually abolishes transplantable glioblastoma growth in mice, probably by the dominant-negative mechanism formation with VEGF receptors of membrane bridging endothelial cells. Embryonic stem cells, which normally grow as solid tumors in nude mice, do not produce detectable tumors when both VEGF alleles are removed. Taken together, these data indicate the role of VEGF in the growth of solid tumors. Inhibition of KDR or Flt-1 has an effect on pathological angiogenesis, and these receptors are useful in the treatment of diseases in which angiogenesis is part of an overall pathology, such as inflammation, diabetic retinal vascularization, as well as various forms of cancer, as tumor growth is known that is dependent on angiogenesis (Weidner et al., N. Engl J. Med., 324, pp. 1-5, 1991).

Accordingly, it is desirable to identify small compounds that specifically inhibit, regulate and / or modulate the transmission of tyrosine kinase signals, and it is an object of the present invention.

(A)

When any variable (e.g., R ⁴ , R ⁶ ; R ^6a, etc.) occurs more than once in a component, its definition at each occurrence is independent of each other occurrence. Combinations of substituents and variables are also permissible only if such combinations result in stable compounds. Lines drawn into ring systems from substituents indicate that the indicated bond may be attached to any substitutable ring carbon atom. If the ring system is polycyclic, it is contemplated that the bond is bonded to any suitable carbon atom on the nearby ring only.

It is contemplated that the substituents and substitution patterns of the compounds of this invention may be selected by those skilled in the art to provide compounds that are chemically stable and that can be readily synthesized using techniques known in the art as well as by the methods described above. , from readily available starting materials. When a substituent itself is substituted by more than one group, it is believed that these multiple groups may be on the same carbon or on different carbons if this results in a stable structure. The term "optionally substituted with one or more substituents" is to be understood as equivalent to "optionally substituted with at least one substituent" and in such cases the preferred embodiment will have from zero to three substituents.

Herein, the term "alkyl" is intended to include both branched and straight chain as well as cyclic saturated aliphatic hydrocarbon groups having a specified number of carbon atoms. For example, C 1 -C ₁₀ as in "C 1 -C 10 alkyl" is intended to include groups having 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 carbons in a linear or branched configuration. For example, _"C-C-alkyl" specifically includes methyl, ethyl, n-propyl, i-propyl, n-butyl, t-butyl, t-butyl, pentyl, hexyl, heptyl, octyl, nonyl, decyl and the like. The term "cycloalkyl" means a monocyclic saturated aliphatic hydrocarbon group having a specified number of carbon atoms. For example, "cycloalkyl" includes cyclopropyl, methylcyclopropyl, 2,2-dimethylcyclobutyl, 2-ethylcyclopentyl, cyclohexyl and the like.

"Alkoxyl" means a cyclic or non-cyclic alkyl group with an indicated number of carbon atoms attached through an oxygen bridge. "Alkoxy" therefore includes the above definitions of alkyl and cycloalkyl.

Unless the number of carbon atoms is specified, the term "alkenyl" refers to a non-aromatic hydrocarbon radical, straight, branched or cyclic, containing from 2 to 10 carbon atoms and at least one carbon-carbon double bond. Preferably, one carbon-carbon double bond is present, and up to four non-aromatic carbon-carbon double bonds may be present. Thus, "C ₂ -C ₆ alkenyl" means an alkenyl radical having from 2 to 6 carbon atoms. Alkenyl groups include ethenyl, propenyl, butenyl and 2-methylbutenyl and cyclohexenyl. A straight, branched or cyclic moiety of an alkenyl group may contain double bonds and may be substituted when a substituted alkenyl group is designated.

The term "alkynyl" denotes a straight, branched or cyclic hydrocarbon radical containing from 2 to 10 carbon atoms and at least one carbon-carbon triple bond. Up to three carbon-carbon triple bonds may be present. Thus, "C ₂ -C ₆ alkynyl" means an alkynyl radical having from 2 to 6 carbon atoms. Alkynyl groups include ethynyl, propynyl and butynyl, 3-methylbutinyl and the like. A straight, branched or cyclic moiety of an alkynyl group may contain triple bonds and may be substituted when it denotes a substituted alkynyl group.

In certain instances, substituents may be defined with a range of carbons that includes zero, such as (C _{0 -C)} alkylene-aryl. When aryl is taken as phenyl, this definition includes phenyl itself as well as -CH ₂ Ph, -CH ₂ CH ₂ Ph, CH (CH ₃ ) CH ₂ CH (CH ₃ ) Ph, and the like.

As used herein, the term "aryl" is used to mean any stable monocyclic or bicyclic carbon ring of up to 7 atoms in each ring, wherein at least one ring is aromatic. Examples of such aryl elements include phenyl, naphthyl, tetrahydronaphthyl, indanyl, biphenyl, phenanthryl, anthryl or acenaphthyl. In cases where the aryl substituent is bicyclic and one ring is non-aromatic, the coupling is believed to be via an aromatic ring.

The term heteroaryl is used herein to represent a stable monocyclic or bicyclic ring of up to 7 atoms in each ring, wherein at least one ring is aromatic and contains from 1 to 4 heteroatoms selected from the group consisting of O, N and S. Heteroaryl groups within the scope of this definition include, but are not limited to: acridinyl, carbazolyl, cinolinyl, quinoxalinyl, pyrazoyl, indolyl, benzotriazolyl, furanyl, thienyl, benzothienyl, benzofuranyl, quinolinyl, isoquinolinyl, oxazolyl, isoxazolyl, indolyl, pyrazinyl, pyrazinyl, pyrazinyl, pyrazinyl, pyrazinyl, pyrazinyl , pyridinyl, pyrimidinyl, pyrrolyl, tetrahydroquinoline. As is apparent from the definition of hetero-cycles, "heteroaryl" also includes the N-oxide derivatives of any nitrogen-containing heteroaryl. In cases where the heteroaryl substituent is bicyclic and one ring is non-aromatic or contains no heteroatoms; the bond is believed to be via an aromatic ring or a heteroatom-containing ring.

As will be recognized by one skilled in the art, the term "halo" or "halogen" as used herein includes chlorine, fluorine, bromine and iodine. The term "heterocycle" or "heterocyclyl" as used herein means a 5- to 10-membered aromatic or non-aromatic heterocycle containing from 1 to 4 heteroatoms selected from the group consisting of O, N and S, and includes bicyclic groups. "Heterocyclyl" therefore includes said heteroaryls as well as their dihydro- and tetrahydro-analogs. Further examples of "heterocyclyl" include, but are not limited to, the following groups: benzoimidazolyl, benzofuranyl, benzofurazanyl, benzopyrazolyl, benzotriazolyl, benzothiophenyl, benzoxazolyl, carbazolyl, carbolinyl, cinolinyl, furanyl, imidazolyl, indazolinyl, indolyl, indolenz, indolaz, indolaz, indolaz, indolaz, indolaz , isoindolyl, isoquinolyl, isothiazolyl, isoxazolyl, naphthopyridinyl, oxadiazolyl, oxazolyl, oxazoline, isoxazoline, oxetanyl, pyranyl, pyrazinyl, pyrazolyl, pyridazinyl, pyridopridinyl, pyridazinyl, pyridyl, pyrimidyl, tetolyl, quinazolinyl, quinazolinyl, quinazolinyl, quinazolinyl, quinazolinyl, quinazolinyl, quinazolinyl, quinazolinyl, quinazolinyl , thiadiazolyl, thiazolyl, thienyl, thiazolyl, azetidinyl, 1,4-dioxanyl, hexahydroazepinyl, piperazinyl, piperidinyl, pyrrolidinyl, morpholinyl, thiomorpholinyl, dihydrobenzimidazolyl, dihydrobenzofuranyl, dihydrobenzothiophenyl, dihydro-benzoxazolyl, dihydro-benzoxazolyl, dihydro-benzoxazolyl, dihydro-benzoxazolyl, dihydro-benzoxazolyl, , dihydrooxa zolyl, dihydropyrazinyl, dihydropyrazolyl, dihydropyridinyl, dihydropyrimidinyl, dihydropyrolyl, dihydroquinolinyl, dihydrotetrazolyl, dihydro-thiadiazolyl, dihydrothiazolyl, dihydrothienyl, dihydrotriazolyl, dihydroazetidinyl, tetrahydrothiothiothiol, oxylenedioxybenzoyl, oxylenedioxybenzoyl, oxylenedioxybenzoyl. The attachment of the heterocyclic substituent may be via a carbon atom or through a heteroatom.

Alkyl, alkenyl, alkynyl, cycloalkyl, aryl, heteroaryl and heterocyclyl substituents may be unsubstituted or unsubstituted, unless otherwise specified. For example, (C 1 -C ₆ ) alkyl may be substituted with one or more substituents selected from: OH, oxo, halogen, alkoxy, dialkylamino or heterocyclyl such as morpholinyl, piperidinyl and the like. In the case where one substituent is oxo and the other OH, the following groups are included in the definition: - (C = O) CH ₂ CH (OH) CH ₃ , - (C = O) OH, -CH ₂ (OH) CH ₂ CH (O) and the like.

These compounds are useful as pharmaceutical agents for mammals, especially humans, for the treatment of tyrosine kinase dependent diseases. Such diseases include tumor cell proliferation, pathological neovascularization (or angiogenesis) that promotes solid tumor growth, ocular neovascularization (diabetic retinopathy, age-related macular degeneration, and the like) and inflammation (psoriasis, rheumatoid arthritis, and the like).

The compounds of the invention may be administered to patients in the treatment of cancer. These compounds inhibit tumor angiogenesis, thereby affecting tumor growth (J. Rak et al., Cancer Research, 55: 4575-4580, 1995). The anti-angiogenesis properties of these compounds are also useful for the treatment of some forms of blindness associated with retinal vascularization.

The disclosed compounds are also useful for the treatment of some bone pathologies, such as osteosarcoma, osteoarthritis and rickets, also known as oncogenic osteomalacia. (Hasegawa et al., Skeletal Radiol., 28, pp. 41-45, 1999; Gerber et al., Nature Medicine, Vol. 5, No. 6, pp. 623-628, June 1999). And since VEGF directly promotes osteoclast bone resorption by KDRZF1k-1 expressed by mature osteoclasts (FEBS Let. 473: 161-164 (2000); Endocrinology, 141: 1667 (2000)), these compounds are also useful for the treatment and prevention of conditions associated with bone resorption such as osteoporosis and Paget's disease.

The claimed compounds can also be used to reduce or prevent tissue damage that occurs after cerebral ischemic events such as stroke, by reducing cerebral edema, tissue damage, and reperfusion injury following ischemia (Drug News Perspect 11: 265-270 (1998) J. Clin Invesi 104: 1613-1620 (1999)).

For oral administration in capsule form, useful diluents include lactose and dried corn starch. When aqueous suspensions for oral use are desired, the active ingredient is combined with an emulsifying and suspending agent. If desired, some sweetening and / or flavoring agents may be added. Sterile solutions of the active ingredient are usually prepared for intramuscular, intraperitoneal, subcutaneous and intravenous use, and the pH of these solutions should be suitably adjusted and buffered. For intravenous use, the total concentration of dissolved compounds should be controlled to ensure preparation of the isotonic solution.

The compounds of this invention may also be administered in conjunction with other well known therapeutic agents that are selected according to their particular utility against the conditions being treated. For example, in the case of bone-related disorders, combinations that might be useful include combinations with antiresorptive bisphosphonates such as alendronate and risedronate; integrin blockers (defined below) such as ανβ3 antagonists; conjugated estrogens used in hormone replacement therapy such as PREMPRO®, PREMARIN® and ENDOMETRION®; selective estrogen receptor modulators (SERMs) such as raloxifene, droloxifene, CP-336,156 (Pfizer) and lasofoxifene; katespine K inhibitors; and proton pump ATP inhibitors.

These agents are also useful, alone or in conjunction with platelet fibrinogen receptor (GP IIb / IIIa) antagonists, such as tirofiban, for inhibiting cancer cell metastasis. Tumor cells can activate platelets, in particular through the generation of thrombin. This activation is associated with the release of VEGF. VEGF release enhances metastasis by increasing extravasation at the endothelial vascular adhesion points (Amirkhosravi, Platelets 10, 285-292, 1999). Therefore, these agents may serve to inhibit metastasis, alone or in conjunction with GP IIb / IIIa antagonists. Examples of other fibrinogen receptor antagonist compounds include abciximab, eptifibatide, sibrafiban, lamifiban, lotrafiban, cromofiban, and CT50352.

II. Human umbilical vein endothelial cell mitogenesis assay

Human umbilical vein endothelial cells (HUVEC) proliferate in response to VEGF processing in culture and can be used as a test system to quantify the effects of KDR kinase inhibitors on VEGF stimulation. In the assay described, the immobilized HUVEC monolayer is treated with vehicle or test compound 2 hours before the addition of VEGF or basic fibroblast growth factor (bFGF). The mitogenic response of VEGF or bFGF is determined by measuring the incorporation of [ ³ H] thymidine into cellular DNA.

Materials

HUVEC cells: Frozen HUVEC as primary culture isolates were obtained from Clonetics Corp. Cells were maintained in endothelial growth medium (EGM; Clonetics) and used for mitogenic assays described in section 3-7 above.

Culture plates: NUNCLON 96-well polystyrene tissue culture flame (NUNC # 167008).

Test medium: Dulbecco's Eagle's medium containing 1 g / ml glucose (low glucose DMEM; Mediatech) plus 10% (v / v) fetal bovine serum (Clonetics).

Test Compounds: Working stock test compounds were diluted sequentially in 100% dimethylsulfoxide (DMSO) to more than 400-fold their desired final concentration. Final dilutions to 1X concentration were made directly in the assay medium immediately before addition to the cells.

10X Growth Factors: Human VEGF ₆₅ (500 ng / ml; R&D Systems) and bFGF (10 ng / ml; R&D Systems) solutions were prepared in a test environment.

10X [ ³ H] Thymidine: [Methyl- ³ H] Thymidine (7.4 x ^{10 11} Bq (20 Ci) / mmol; Dupont-NEN) was diluted to 2.96 x ^{10 6} Bq (80 pCi) / ml in low glucose DMEM.

Cell wash medium: Hank's balanced saline (Mediatech) containing 1 mg / ml bovine serum albumin (Boehringer-Mannheim).

Cell lysis solution: 1 mol / l NaOH, 2% (w / v) Na ₂ CO ₃ .

method

1. HUVEC monolayers maintained in EGM were harvested by trypsinization and plated at 4000 cells per 100 µl assay medium in a 96-well plate. The cells were grown for 24 hours at 37 ° C in a humidified atmosphere containing 5% CO ₂ by weight.

2. The growth medium was replaced with 100 μΐ of test medium containing either vehicle (0.25% (v / v) DMSO) or the required final concentration of test compound. All assays were performed in triplicate. The cells were then incubated at 37 ° C with 5% CO ₂ for 2 hours, allowing the test compounds to enter the cell.

3. After 2 hours pretreatment, cells were stimulated by adding 10 μΐ / wells of either assay medium, 10X VEGF solution or 10X bFGF solution. Cells were incubated at 37 ° C and 5% CO ₂ .

4. After 24 hours in the presence of growth factors, 10X [ ³ H] thymidine (10 μΐ / well) was added.

5. Three days after the addition of [ ³ H] thymidine, the medium was aspirated off and the cells were washed twice with a cell wash medium (400 μΐ / well and then 200 μΐ / well). The washed, adherent cells were then solubilized by the addition of a cell lysis solution (100 μΐ / well) and heated to 37 ° C for 30 minutes. Cell lysates were transferred to 7 ml glass scintillation vials containing 150 μΐ of water. Scintillation solution (5 ml / ampoule) was added and cell-associated radioactivity was determined by liquid scintillation spectroscopy.

Based on the foregoing assays, the compounds of formula (I) are VEGF inhibitors and thus are useful for inhibiting angiogenesis, such as in the treatment of ocular diseases such as diabetic retinopathy and in the treatment of cancers such as solid tumors. These compounds inhibit VEGF-stimulated mitogenesis of human vascular endothelial cells in culture with IC ₅₀ values between 0.001 to 5.0 pmol / L. These compounds may also have selectivity for related tyrosine kinases (e.g., FGFR1 and Src family; for relationship between Src kinases and VEGFR kinases, see Eliceiri et al., Molecullar Cell, Vol. 4, pp. 915-924, December 1999).

The examples provided are intended to assist in further understanding the present invention.

In particular, the materials, compounds, and conditions employed are intended to further illustrate the present invention and not to limit its reasonable scope.
